Answer:

32m^4 + 12m^3 = 4m^3(8m + 3)  ---------->correct

40m^6 - 4 = 4(10m^6 - 1) ---------->correct

Step-by-step explanation:

32m^4 + 12m^3 = 4m^3(8m + 3)  ---------->correct

40m^6 - 4 = 4(10m^6 - 1) ---------->correct

15m^3 - 6m = 3m(5m^2 - 2) , so it's not correct if answer : 3m(5m^2 - 6m)

6m^2 + 18m = 6m(m + 3) , so it's not correct if answer : 6m^2(1 + 3)
